After updating I lost all my accounts!

NOTE: THE FOLLOWING ONLY APPLIES WHEN UPDATING FROM A VERSION PRIOR TO 2.1.38.0.

IF UPDATING FROM A LATER VERSION THIS DOES NOT APPLY AND YOU SHOULD CONTACT SUPPORT INSTEAD.

We sincerely apologize for the trouble. This occured because Mailbird was unable to move the database and a couple of other folders to their new location, but don't worry, your accounts and messages are all safe. Here is how to get them back:

Close Mailbird.

Open Windows Explorer and in the address bar at the top type: %localappdata% and hit Enter. Alternatively, hold down the Windows key on your keyboard while pressing the R key. This will bring up the Run window where you can type %localappdata% and click OK to open the folder.

In this folder you will find a subfolder called 'Mailbird'. Open this.

Inside this folder delete the subfolder called 'MessageIndex' if it exists. It may not.

You may also find a folder called 'Attachments'. If you do, rename it to simply the capital letter 'A' (by selecting it and pressing F2 on the keyboard, then removing letters until only the first A is left, and pressing Enter on the keyboard).

Now move the folder 'A' to inside the folder called 'Store', by dragging and dropping the 'A' folder unto the 'Store' folder. If asked to replace files, click yes. We want to replace files and folders inside.

The 'A' folder should have disappeared from the folder.

Open the 'Store' folder.

Delete the 'MessageIndex' subfolder in here as well, if it exists.

Inside you may also see 1 to 3 files starting with the name 'Store.db'. If you do, delete them all. This is the new database that was created after you updated which does not hold your old accounts, so is safe to delete.

Now go back out one "level" to the main 'Mailbird' folder again.

Here you will see the same 1 to 3 files starting with the name 'Store.db'. Move all these files inside the 'Store' folder, the same way as before with the 'A' folder. These are the old database files with all your accounts and messages. Moving them to their new location inside the 'Store' folder will let Mailbird use them again from now on.

That should fix it. If you start Mailbird now, all your accounts and messages should have returned.

Note Mailbird may appear a little laggy and use more CPU for a few minutes, while the message index is recreated.

If you experience any issues following this guide, please don't hesitate to create a support ticket and we will get back to you as soon as possible.
